“…During the last few years a number of promoters active in different stages of plant development, namely in germline Van Ex et al, 2009), embryo , microspore (Mlynarova et al, 2006;Luo et al, 2007), floral (Bai et al, 2008) and seed (Odell et al, 1994;Moravčíková, et al, 2008;Kopertekh et al, 2010) tissues have been tested to control cre expression. High efficiency of such promoters in Arabidopsis , tobacco (Mlynarova et al, 2006), rice (Bai et al, 2008), soybean (Lie et al, 2007) and oilseed rape (Kopertekh et al, 2009) makes this approach universal for model and agronomically important species.…”
